This study aims to evaluate a questionnaire used by a specialized nurse to help manage relapses in people with multiple sclerosis (MS). The questionnaire is completed during a phone call when the patient reports new or worsening symptoms. It helps the nurse decide whether further tests or treatments are needed, based on a protocol developed with a neurologist. The goal is to improve how quickly and effectively patients receive care during a relapse. The study will include 10 adult patients with active forms of MS over a two-month period.

Inclusion Criteria:

• Patients followed by Dr. Manchon for Relapsing-Remitting Multiple Sclerosis or active Secondary Progressive Multiple Sclerosis
• Adult patients (aged 18 or older)
• Patients who have provided informed consent for participation in the local task-sharing protocol

Exclusion Criteria:

• Pregnant women
• Minors (under 18 years old)
• Patients with known renal failure
• Patients who have not provided or are unable to provide consent for the local task-sharing protocol

The participants will be selected from adult patients with Multiple Sclerosis (MS) who are under the care of Dr. Manchon at a single neurology center. Specifically, the population includes individuals diagnosed with either Relapsing-Remitting MS or active Secondary Progressive MS. All participants must have provided informed consent to be included in a local task-sharing protocol that allows a specialized nurse (IDEC) to conduct initial evaluations during suspected relapses. This population reflects patients who are actively monitored for MS and may experience acute neurological symptoms requiring timely assessment and intervention.
